Abstract (en)
[origin: US4609574A] An improved, curable, silicone, release coating composition is provided which cures more rapidly, at lower temperature, and with less residual reactive functionality. The composition contains siloxane polymers bearing higher alkenyl groups with 6 or more carbon atoms and cures by the metal catalyzed reaction of SiH with the alkenyl groups. An improved on-line process for preparing release laminates of substrates and adhesive using the coating composition is further provided.
